This library support nested scroll for refresh and load more,so you can use it with CoordinatorLayout and AppBarLayout and so no.You can design your self header or footer easily. 中文文档

Add Header

   CircleHeaderView header = new CircleHeaderView(getContext());
    mRefreshLayout.addHeader(header);

Add footer

FootView footView = new FootView(getContext());
mRefreshLayout.addFooter(header);

Callback

you should make Header impl HeaderListener,so you can know the refresh state.and to Footer with FooterListener.

mRefreshLayout.setOnRefreshListener(new OnRefreshListener() {
    @Override
    public void onRefresh() {
		//doRefresh
    }

    @Override
    public void onLoadMore() {
      //doLoadmore
    }
});

Layout

<com.lovejjfg.powerrefresh.PowerRefreshLayout
android:id="@+id/refresh_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler"
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="com.lovejjfg.demo.MainActivity">
    </android.support.v7.widget.RecyclerView>

</com.lovejjfg.powerrefresh.PowerRefreshLayout>

Tips

• If you want to refresh when first init call setAutoRefresh(true) on MainThread.

• If you don't want to add any Footer,but loadmore, you should call setAutoRefresh(true) ,and at last, you should call setLoadEnable(mAdapter.getList().size() < 50) to make RefreshLayout konw whether is there any more nor not.

• Refresh finish,you should call stopRefresh(boolean isSuccess) to make RefreshLayout konw that refresh is over,then the header will disappeared as soon as possible. if you want header disappeare delay, you can call stopRefresh(boolean isSuccess, long delay)

• which height should go to start refresh ? If height is not specified,the default is the header's height. you can return the height by impl HeaderListener:

    @Override
    public int getRefreshHeight() {
        return (int) (getMeasuredHeight()*0.8f);
    }
  

• If there is only one header or footer in you project ,dont forget to extend PowerRefreshLoayout and add header or footer once.
